摘　　要：建立了导管高频感应钎焊过程的有限元分析模型,分析了不锈钢导管的高频感应钎焊过程中的温度场并与试验结果进行了对比,仿真结果和试验结果基本吻合。在此基础上,研究了接头形式、感应电参数(电流频率、电流密度)对钎焊过程的影响。结果表明,接头的体积越大,升温效率越低。随电流频率和电流密度的增加,钎料熔化所需的时间逐渐减少。另外,采用较高的电流频率和电流密度能有效降低接头形式对钎焊过程的影响。A FEM model on high frequency induction brazing process of the pipeline components was developed. The temperature field in the pipeline components for induction brazing process was simulated and compared with the experiment results. Based on the model, the effects of the joint shape and the induced current parameters on the brazing process were investigated. The results show that, as the volume of the joint increased, the heating time would be longer. The time of the solder melting reduced as the frequency and the density of the current increased. Moreover, the effects of the joint shape on the brazing process could be effectively reduced by employing high current frequency and high current density.
